ATTORNEYS United States Patent Olfice 3,447,212 Patented June 3, 1969 U.S. C]. 28-49 5 Claims ABSTRACT OF THE DISCLOSURE A warp tying machine includes one or more frames each having a guide for a warp tying attachment. The attachment is movable along the guide for the purpose of tying the warp threads to be used on a weaving machine. The warp tying frame includes one or more tying attachment guides which are arranged so that they may be displaced laterally or provided with an extension which may be either moved laterally or connected on the side edge of the existing guide for the purpose of providing a support and guide for the tying attachment extending beyond one side of the frame in order to facilitate the tying in operation for the warp threads especially Where more than one warp beam is provided.

SUMMARY OF THE INVENTION This invention relates in general to warp thread tying machines for tying in warp threads to be used on weaving machines and in particular to a new and useful warp thread tying machine having a guiding frame for a tying attachment which may be located so as to extend outwardly from one side of the frame.

Frames for conventional warp tying machines are usually long enough to enable the warp to be tied to be spread over the entire width of the frame leaving enough space on one end to permit the positioning of a tying-in attachment at this end. Unfortunately tying frames of this kind are extremely cumbersome for tying warps on weaving machines which have effective width which cover more than one warp beam. In addition, it is extremely difiicult and time consuming to spread the warps over the entire width and it often has to be carried out by two people. Heretofore it has been impossible to use normal width tying frames on each individual warp beam because the frames have to be oriented very closely together so that they do not leave enough space between the individual layers of warp threads for the warp tying machine to be switched from one frame which has warped threads which are already tied to the adjacent frame with warps to be subsequently tied.

In accordance with the present invention there is provided a frame for warp tying machines which includes guides which are extendablc or positionable on at least one side of the frame so that they provide means for mounting the Warp tying machine or tying attachment at a location outside the frame. To this end the frame is constructed so as to be laterally extensible or is provided with means for holding projecting guide portions which form attachment guide continuations extending laterally beyond the edge of the frame or between adjacent frames.

Accordingly, it is an object of the invention to provide an improved frame for warp tying machines which includes warp tying attachment guide means which are located to one side of the frame.

A further object of the invention is to provide a warp tying frame which is simple in design, rugged in construction and economical to manufacture.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and specific objects attained by its used, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated and dc scribed a preferred embodiment of the invention.

BRIEF SOLUTION OF THE DRAWINGS In the drawings:

FIG. 1 is a diagrammatical front elevation of two warp tying frames arranged alongside each other;

FIG. 2 is a View similar to FIG. 1 with one of the frames displaced away from the other and with the tying in apparatus shifted to the second frame; and

FIG. 3 is an enlarged partial perspective view of a frame having a tying-in attachment extending to one side as constructed in accordance with the invention.

DETAILED DESCRIPTION Referring to the drawings in particular, there is indicated in FIG. 1 two tying frames 1 and 1 which are arranged alongside each other in a position which is necessary when working with weaving machines comprising at least two adjacent warp beams. The sides of one end of the tying frames 1 and 1 do not have any projecting parts so that there will not be any additional gaps or intervals required between the layers of warp threads of each frame. The warps 2 and 2' of each beam 3 and 3 are arranged in spaced parallel relationship on the frames.

Devices 20 and 20' for stretching and preparing the warps 2 and 2 are arranged at those ends of the frames '1 and 1', respectively, which are remote from one another so that the handcranks on each extend outwardly in respective opposite directions. A tying attachment or tying machine 4' is initially mounted on the frame 1 at the dotted line position indicated and then advanced (warp machine 4) to the left in the direction of the arrow to complete the tying operation. After the warp 2 has been tied, the tying attachment 4 is moved above the left-hand edge of the warp 2' and it must be attached in front of the right-hand edge of the warp 2', that is, it requires guides projecting beyond the frame 1'. Since, however, the adjacent frames indicated in FIG. 1 are constructed so that they do not leave enough space between them for a support of this kind, the guide means of the frame 1' is provided with a tying-in attachment guide which may be either displaced laterally outwardly beyond the side of the frame or it may receive an extension piece so that the guide is extended laterally to permit easy placement of the tying-in attachment after the other frame is moved out of the way. In the embodiment illustrated in FIG. 3 the guide elements 11, 11 which are carried by the frame 1 may be mounted so as to be laterally displaceable or as indicated they are provided with socket recesses 16 and 17, respectively, for receiving projecting pieces 14 and 15 of guide extensions 12 and 13, respectively. The construction is such that the tooth formation 11a of each of the guides 11 is continued as formations 11a on each of the extensions 12 and .13. Either the sockets 16 and 17 or the projection portions 14 and 15 are provided with suitable locking means (not shown) for locking the extensions 12 and 13 in a desired positlon.

It should be appreciated that the gap between frames 1 and 1 may be bridged by guides 11 which may be extended between the two frames or by separate extensions or extensible parts of the guides so that the tying in machine 4 may be transported on the guides from one frame to the other. For example, the guides 11 which are illustrated in FIG. 3 are advantageously mounted so that they may be displaced on appropriate trackways in lateral directions in order to form a support projecting beyond the end of the frame for the tying-in machine so that they can be returned within the frame as required.

The subdivision of the effective width of the weaving machine so that it covers more than one frame has the advantage that compared to its single full length frames the first component Warp 2 is initially prepared and made ready for tying and this may be easily followed by the preparation of the second component warp 2' and so on. When the tying attachment'begins work on the second warp 2, the first component warp 2 can be removed from the frame 1. This means that a considerable saving in time can be achieved because it is possible to continuously carry out the preparation, tying and release of the individual component warps in succession so that there is no need to wait for the end of the preceding operation before beginning the next operation.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.

What is claimed is:

I. In a frame for preparing Warp threads for weaving machines including a frame with a warp beam over which the warp threads are arranged, the improvement comprising a warp tying machine guide extending across said frame and including a guide portion which extends outwardly from one side of said frame whereby the tying machine may be moved on said guide means outside said frame for transportation thereon to the frame of an adjacent machine.

2. In a frame according to claim 1, wherein said guide portion of said guide means includes a separate guide member forming an extension.

3. In a frame according to claim 1, wherein said guide portion includes a separate guide member adapted to bridge the space between a plurality of frames.

4. In a frame according to claim 1, wherein said guide portion is formed by shifting said guide means laterally.

5. A method of tying in the warp threads of a plurality of closely arranged frames each having warp beams for weaving machines, comprising arranging the frames in a side-by-side relationship, disposing a tying-in machine on one side of one of said frames and moving said machine along said frame in a direction toward the second adjacent frame to tie in the warp threads on the first frame, providing guide means between the two adjacent frames as a bridge between the frames and means for the trans portation of the tying-in machine from one frame to the next over the bridge whereby the tying-in machine may be moved to the next adjacent frame and the tying in of the said adjacent frame may be carried out while removing the first frame and the tied in warp.
